exe filesize in Delphi 5 & loading time

I have just upgraded from Delphi 2 and have found that my applications are
now considerably larger and their loading time is much slower.

Is there any way to reduce to file size and speed this the loading time?

I have been unable to compile my application using packages see my other
post titled "package 'vclmid50' not found" also in this newsgroup

Your help will be greatly appreciated
